BOX-TOO L.

SPECIFICATION forming part of Letters Patent No. 563,377, dated July '7, 1896.

Application filed September 12, 1895. Serial No. 562,239. (No model.)

To all whom, it may concern:

Be it known that I, WVILLIAM GHUSTON, a

. citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Box-Tools, which improvement is fully set forth in the following specification and accompanying drawings.

My invention relates to box-tools, and consists of a novel construction of device which is adapted to be mounted upon any desired support, and is especially applicable for the manufacture of bolts and similar articles, provision being made for effectively and expeditiously reducing the diameter of the rod or bar from which the bolt or other articleis produced, and means being also provided for quickly and positively adjusting the cuttingtool, so as to reduce the stock or material employed to the desired diameter.

It also consists of novel means for effectively and rigidly holdingthe cutting-tool in the desired position.

It also consists of novel means for adjust: ing said cutting-tool. V i

It further consists of novel details of con struction, all as will be hereinafter set forth.

Figure 1 represents a front elevation of a box-tool embodying my invention. Fig. 2 represents a vertical sectional view of the same, the section being taken on linew 00, Fig. 1. Fig. 3 represents an end elevation of said tool. Fig. 4 represents a front elevation, partly in section, showing a modified form of tool which is especially applicable for manufacturing taper-bolts, &c. Fig. 5 represents a side elevation of Fig. 4. Figs. 6 and 7 represent different forms of tools employed for manufacturing bolts or similar articles having a beveled or recessed shoulder.

Similar letters of reference indicatecorresponding parts in the several figures.

Referring to the drawings, A designates the tool complete, the same consistingof a shank B, which is adapted to be held in'a chuck or any other suitable support, said'shank-having attached thereto the plate or disk 0, from which extends the body portion D, to which latter is attached the plate or disk E. 1

joined throughout their length by means of the said back or body portion'D, as will be understood from Fig. 2, the inner face of said portion D, taken in conjunction with the inner edges of the extensions F and G, forming bearings for the tool-carrier H, which is capable of movement relative to said body D, and has its upper surface provided with a serrated or roughened face J, the purpose of which will be hereinafter set forth, said toolcarrier also having a threaded stem K attached thereto and projecting outwardly therefrom.

L designates a nut or adjusting device, which has a portion milled or knurled, so as to be readily manipulated with the fingers, said nut'having a neck M, which enters the cap N, which latter is supported and secured upon the upper face of the portions F, D, and G, the extremity P of said neck being adapted to rest upon a suitable shoulder on said back or body portion D, as will be understood from Fig. 2. The said nut or adjusting device L is interiorly threaded, so as to be engaged by the threaded stem K, said nut being swiveled in said cap N in any suitable manner, the means in the present instance being the annular groove Q, the walls of which are engaged by the extremity of the stud or pin R, which enters the cap N, whereupon it willbe seen that upon rotation of the nut or adjusting device L in the desired direction a corresponding movement will be imparted to the toolcarrier H by reason of the engagement of the threaded stem K with said nut.

The tool-carrier is provided with an elongated slot S, through which passes the threaded stem or stud T,which is secured in said body D in any convenient manner, said stem passing through the slotted plate U, which, when r the parts'are in assembled position, is adapted to have'one edge rest upon thecutting-tool V, while its other edge is supported upon the filling-piece W, which in the present instance is rigidly attached to the tool-carrier H, it being noted that the under side of said cuttingtool V, which is in contact with the serrated or roughened face J of the tool carrier H, is provided with corrugations or serrations corresponding to said tool-carrier, so that when the parts are in assembled position, and are ICO held rigid or locked by the nut X, the cuttingtool V will be positively and efiectively held rigid with respect to the article which is being manufactured, as will be explained.

The portion E is provided with a hole or passage Y therethrough, within which is located a bushing Z, the latter being held in position by means of the screw or pin A or similar devices, it being noticed that the center of said bushing is in alinement with the center of the hole or passage 13, which extends in the present instance throughout the length of the shank B.

In the construction shown in Figs. 4 and 5 the principle of my invention is not departed from, O designating the tool complete, the same having the shank D, within which is a passage E, which latter extends through to the body portion F.

G designates a bushing which is inserted in the lower portion of said body, said bushing and body being cut away or recessed adjacent to the edge of the cutting-tool, as will be understood from Fig. 5.

H designates a roughened plate or toolcarrier which is suitably guided and supported, and corresponds to the plate II in the other figures, upon which is placed the cutting-tool K, the same having its cutting edge out of alinement with the axis of the shank D, and being held in position by means of the slotted plate L, through which passes the stud J, a nut M engaging said stud, and serving to lock and hold the parts firmly in position when desired.

N designates a threaded stem, which is attached to said plate II, which stem is engaged by the swiveled nut or adjusting device Q, which passes through the cap P, the function of said adjusting device relative to said stem being the same as already described with respect to the other figures, and being best seen in Fig. 2, it being noted that the contactingsurfaces of the cuttingtool K and the carrier H are serrated or roughened, as has been described with respect to the other figures. R designates a passage within said tool, through which the chips formed in the-operation of making the bolt or other article escape.

S and T designate different cutting-tools which may be employed, the same being provided with the angular or beveled shoulders V U, respectively, which may be employed for different kinds of work, as desired.

XV designates a portion of a taper-bolt, the same being shown in the process of manufacture, and being operated upon by the cuttingtool K.

X designates a rod or bar in the act of being operated upon by the tool shown in Fig. 1, the portion Y having been reduced to the desired diameter, as will be hereinafter explained.

The operation is as follows: The parts are best seen in assembled position in Fig. 2, it being evident that the cutting-tool V is immovably held with respect to the tool-carrier H by means of the plate U and the nut X, and it will be seen that a very delicate adjustment can be given to said tool-carrier by loosening the nut X and rotating in the proper direction the nut or adjusting device L, the parts being locked in the desired position, when the proper adjustment has been eifectechby means of said nut X. The stock X, which may be a rod or bar, is rotated and inserted within the bushing Z, and caused to advance in the direction of the arrow in Fig. 1, and as the same is rapidly rotated, and the cutting-tool V being held stationary, it will be evident that the contact of said cutting-tool with the advancing stock or material X will cause the same to be quickly and effectively reduced to the desired diameter, as at Y, the bolt, after having been operated upon in the manner described, being afterward cut off at the desired length, the operation being repeated in the manufacture of successive bolts.

In Fig. 4 the manner of assembling and operating the parts is substantially the same as already described, the cutting-tool K and the bushing G, however, converging toward each other, whereby it will be seen that a taper-bolt or similar article can be readily produced, the manner of adjusting and locking the parts being the same as already described.

' lVhen desired, the cutting-tools T or S may be employed, the function of the same being as already described.

It will of course be apparent that changes may be made in the manner of assembling the parts by those skilled in the art that will come within the scope of my invention, since other means than the adjusting device L may be employed, and other means may also be utilized for locking the parts in desired position according to requirements, and I do not therefore desire to be limited in every instance to the exact construction I have herein shown and described.

The serrated or roughened contacting faces of the cutting-tool and the tool-carrier cause the same to be held rigidly in juxtaposition when the nut X is tightened, and when the same is loosened delicate and exact adjustment can be given to said tool-carrier and cutting-tool by the proper manipulation of the adjusting device L, as is evident.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A box-tool consisting of a hollow shank, with disks having lateral extensions and conneeting-body,a tool-carrier adjustable on said body, and a clamping device for said carrier and tool, said disks having openings in line with the center of the bore of said shaft, and said carrier being guided on the inner face of said disks, said parts being combined, substantially as described.

2. In a device of the character described, a shank with disks having a connectingbody, a nut swiveled in a cap on said body, a toolcarrier with threaded shank working in said nut, and a clamping device for said carrier, said disks having openings therein, said parts being combined substantially as described.
